This is my fourth transaction with sim-unlock. It took longer than usual (past the 7-day TAT) but they eventually delivered. Still, I'd recommend this service, especially to phone owners in the Philippines. Thanks and keep up the good work.

Less than 48 hours and got the unlock code for my AT&T branded Lumia 640 LTE. Carrier refused to unlock it and thought I was out of luck. Very reasonable fee and now my 640 is unlocked and I have since flashed it to use in Mexico and Canada.

I received the unlock code within 24hours....and it worked I had tried two different companies before which have failed.

2016-02-22 16:18:25 James

Less that 24 hours to respond and the code worked just like that. Well worth the very small fee.

Not for the first time I am using the service of sim-unlock.net and as always it is a first class service in less than 3 days I got my code for a Lumia 640 LTE and it worked perfectly.

2016-02-04 06:34:38 Jean

Je suis très satisfait de ma commande chez unlock mobile... J'habite en France.. J'ai acheté mon smart phone aux Etats-Unis et Unlock mobile m'a obtenu le code de déblocage en moins de 24 heures..Cela a marché du premier coup. C'est rapide et pas cher Je recommande ce site et je garde ses coordonnées au cas où j'aurai à nouveau besoin de leurs services

2016-02-03 21:24:37 Aaron

Took a bit long but it worked

2016-01-15 08:37:13 Shawn

This is the 3rd phone I've unlocked through sim-unlock.net and they've worked very well at reasonable timelines. I would definitely recommend them to a friend.
